Be it kndwn that -I, THOMAS JfSIloA'N, ot' lNew York, of New Yorkcounty, inthe State of New York, have invented certain new anduseful'lmprovements in Apparatus for Opening'and Closing Window-Blindsand I do hereby ldeclarethat the following is a. full and lexa'ctdescription thereof, reference being-'had tothe accompanying drawings,making parti of this application. Y

My invention relates to devices for opening and1closing outside'shutters and lockingthem.

Previous tomy invention numerous devices have been suggested foreiiecting, from within the window, the

shutter in its opened and closed positions. W My present inventionrelates,` in'theiirst place, to a novel means or device for openingandclosingl the blind;

opening and closing of4 outsideshlutters of windows, and-such devices as'have been made'toiretain or hold the whichfcan be 'worked withoutopening the window.

secondly, to the application, in connection 'with an opening. andclosing-mechanism, ofa positive lock-mechanism,

It is all-important, in the use of any opening and closing-device,designed to avoidjthe' necessity-of opening and closing` vthe window, toprovide some preventive `-to theshut'ters becoming,r deranged and wedgedtogether, since, when such occurrencetakes place, no mechanism forvopening the blind will effect that desired end; and it is oftennecessaryto positively lock the blinds, and 'is-always desirable to'drawthem, when closed, tight home, so as to keep the blindstt'rue', vand ingood order.v I i Y -l The first part of my invention consists ina'novelineehanism for opening and closing and retaining the shutterwithout openingv `the window, composed of geared: hinge-sectors',taspring-shaft, arranged to slide and rotate, and a retaining-device, allas hereinafter more fully-described. i 4

And my invention further consists'in the employment, inonnection with adevice for opening and-closing the shutter from within the window,.ot`alcoli-mechanism, which is operated also from within the window, as willlbe presently explained. i' i I And my invention further :consists inthe a'pplicationot overlapping lips or a strip, so made and arranged asto eli'ectually prevent the blindsbec'oming deranged orstu'cktogether,as will be more fully explained hereinafter.:

To enable those skilled in the artjto make and usefmy invention, I willproceed to describe the construction and operation of the severalfeatures -ot my invention, referring by letters to theaccompanying'drawings,

making. part of my application, andn which- Figure 1 isY a front'orfacevie'w of ,a windowand( outside shutter,'(with the shut-ter closed,)embrajcing my invention.

Figure 2 is a v erticalsection at-line a'a, igr'l. Figurer?) is a detailview of lockldevice.V Figure 4 is a cros'ssection at b b, iig. 2. AFigure Sisma horizontal seo-tionthrouooh tho. frame, showing thelock-device, and Figure 6 is adetailview, showing insid'eiof shutter-andthe look-plate. f' In ythe several figures the samerparts laredesignated by the same letters of reference.

A'is the window-frame, and an ordinary'outside blind or shutter, hung.to the framobya commonhinge,

C, at the top, and' near the bottom hung` on one of my improvedhinge-devices, as clearly. shown in the drawings. Dis a metallic stand,bolted to the outside ofthe window-frame, andformed with anarm, E, in'which is formed a bearing for the outer end of shaft F,.and also withvan arm, G, in which is'hung a pendant, vndesiggned to retain the blindon its hinges. The upper extremity of arm E forms the supporton which ishung and turns the hinge-gestald, the sta'ndI of which is bolted to theshutter,`as shown; and the outer4 side of said arm E,

near its top, is formed with'a projecting rim, m, which operates,together with 5thepcan or button non shaft-F, to' effect the retentionof the shutter indiierent'positins. Said shaft passes through thewindow-frame in suitable bearings, isrprovidedV with a handle,-J, andis'ra'rranged, sothat it can both rotate and slidevlngitudinally in itsbearings. Said' shaft carries on it. the driving-gear sector K, and ismade square where it PassesthrOugh' the hub of saidlgear, so that whilesaid gear turns with said shaft, the latter is free toslide4longitndnally `within the fermer. l l 1 i each of them, for the purposeof retaining the'shutter in any given position.

lis a; spiral spring arranged around the shaft F, in such manner as tovcontinually press the shaft linthe direction indicated by the arrow,fig. 2. l Y l '.lhe opcrationof this part of my invention maybe'thusfexplained: 4When it is desired to open the blind, the shaft -Fis pressed out longitudinally, A:is illustrated in red,. ig. 2,' untilthe button e'y can 'rotate' past the outer surfa'ce of hub or ri'm m,and in contact' therewith; it'is then rotatedbyits handleJ, which causesthe gear K to turn the gear H, and swing open the shutter. When theshutter has been opened, the button z'p'nsses bach nto`a. deprcssion inthe rim m, and-retains the shutter in position, from which it can bereleased by again pressing out the shaft F, and relieving'the rim m fromthe stop-button z'.

The rim m may be mudelkif de'ernedexpedient, with numerousdepressi,ons,'and the button z' adapted to catch in M and N are metalliclips, fastened tothe overlapping shutter, audarranged to larpl 'wellover and "bear against the outer face ofthe other half of shutter. Theobject and advautage'of these. plates are to`prevent the shutter towhich they are attnehedfromheing drawn or closed in too tight, andcramped with the othershutter,

so as to render the openng-devioe inell'ectualf The lower one, N, ofthese plates serves also as pnrt'ofthe lockdevice, which 'I will nowexplain.

O isla shaftvor rod passing horizontally through the sill of the window,and formed with-a'te or bend, at right angles, onits outer end, whichturns in the lock-plate P. -On the'inner end of rod or shaft O isarranged, with a. feather, a longer collar, g, which is provided with.ahandle, R, eind which,'while it is' free' to more longitudinally onsaid` shaft, turns the said Ashaft with it; i Within the said-collar "qis a spiral-spring, s, which continually presses it towards thewindewframe, andY the end nearest the frame is providedfwith n pdin-t orprojection, which isndapt-edto pass into either of twovholes in theplate t, for the pnrposeof retainingthe collar from turning around, andthuspreirentingithe' turning from without of the loeking-sheft O. Withinthe loch-plate P is an inclinedl bearing-pluma, against which the toe 7"of the locking-shaft hears, and, hymeans o f which incline the saidtoedraws the blind home to its bearings, and loclisit securely.

It will bescen that when the loekin'gfshaft drnwsthe shutter close andfast,'it in tnrn, by meonsvof its overl lapping lip-pieces, draws andholds the othershutter fn'st home.

When the 'shaft O is turned to either of its positions, Athe collar gwill, by means-of itsprojecting teat passing into the holes in platet,hold it securely in suchposition. i v

' Having'fully explained my improvements, so that-one skilled in'- thenrt een, make and usethem,.what I claim as new, and desire to secure byLetters Patent, si v The bevel-gears K H, in combination with thespring-shaft F, retaining-button@ and rim' m, when the fsaid shaftsaranged to drive the gen1-K, and slide longitudinally throughit,'as'an'd'for the lpurpose set forth.'

2. .The employment, in 'connection lwith a. mechanism for opening andclosing blinds from the inside of the window, of a. positivelock-mechanism', composed of the loekingsshaft' O r andspring-retainingmechonism q R s t, alles specified.

In testimony whereof, I hare hereunto set `my halnd lrind seal, this18th of Decemb er,'1867.
